Since dehydration can increase the risk of decompression sickness, it’s important that divers fully understand the science behind why this urge to pee happens when they submerge.

Remember to keep well hydrated when diving and don’t let the urge to pee put you off drinking plenty of water. If the urge hits on your dive (and it will), you’ve got our permission to go with it. However, if the urge to pee persists long after you’ve surfaced, or symptoms such as burning and stinging when you go appear, this could signify a water infection and you should seek medical advice.
